TO ALL WHOM IT MAY CONCEBN:

Be it known that I, J. B. COLLIN, (assigner-.to myself` and R. E.Ricker,) of Altoona, Blair county, Pennsylvania, have invented anImprovement in Oil-Cups; and I do hereby declare the following to be afull, clear, and exact description of the same. i

My invention consists of anoil-cup having an adjustable tapering pinprojecting through an orifice communieatingmith and. smaller than thedischarge-passage, so as to form a regulating-drip or guide forconveying the oil from the 'cup to the said passage, all substantiallyas described hereafter.

The main object of lmy invention is to dispensewith the usual wicks andother objectionable appliances to discharge as much oil only as willmeet the demand for perfect lubrication, and to maintain the oil andinterior of the cup in a clean, ungummed state. i j

In order to enable others skilled in the art to apply my invention, Iwill now proceed to describe the mode of. carrying the same into effect,reference being had to the accompanying drawing, which forms a partei'this specification, and in Whichl Figure 1 is a vertical section of myimproved oil-cup.

Figure 2, a plan view of the same.

Figures 3 and 4 represent a modification of my invention; and

Figures 5 and 6 represent another modification.

Similar letters refer to similar parts throughout the several views.

On reference to figs. 1. and 2, the body or reservoir A of the cup maybe' made of any desired form which the intended application ofthe cupand the taste and judgment of the constructor may suggest as the mostappropriate. The top of the cup is provided with a detachable screw-cap,B, through which passes the stem' of a set-screw, D, and to' the lowerend of the latter is secured the long, tapering, and pointed pin d,which projects into an orifice formed in the top of the tube b, thelatter projecting upwards from the bottom d of thecup into theinterior-of the same. There'is the usual tubular projection e on theunder 'side' of the cup for the attachment of the same to the object tobe lubricated, the interior, ze, of this projection forming, with theinterior of the tube b, the discharge-passage for the oil, and beinglarger in diameter than the orifice through which the pin d projects.

The oil-cup illustratedin figs. 1 and 2 is'intended for application toconnecting-rods, eccentrics,.or other objects, Vthe movement of which issuch that the comparatively small quantity of o'il contained in the cupwill be so agitated as to reach the pin d by which the oil is conductedto the discharge-passage :e in quantities commensurate with the size ofthe annular space between the said pin d and the orifice in the tube z,through which the pin projects. The size of this annular space may beregulated at pleasure by first loosening the jam-nut',f, and thenturning the set-screw D, and-thereby raising or lowering the pin d, ascircumstances mayrequ'ire. It should be' here understood that the objectof the pin is not to serve as a simple valve; in fact, it is neverabsolutely necessary to close this orifice entirely, and rarelynecessary to alter the position of the pin clafter its iirst adjustment,which determines the amount of oil necessary to meet the demand; hencethe pin, viewed in connection with the orifice, may be termed aregulating-conductor or drip, for conveying a givenamount of oil fromthe reservoir to the discharge-passage :'e, the oil iiowing down the piufrom whicbit drops, und not spreading itself on the interior of thepassage az, owing to the latter being larger in diameter than theorifice through which the pin passes.

In figs. 3 and 5 the tube b is much shorter than in g. 1. Thesemodifications of my invention beingintended for application to guidesfor steam-engine cross-heads, or to other objects which remain in such aquiescent, or

,comparatively quiescent state, that there can be little or no agitationof the oil, which, however, can reach the pin d, owing to the shortnessofthe tube In g. 5the pin is attached to the screwcap B, which isfurnished with a screw-plug, F, s'o that, on withdrawing the latter, oilmay be poured 4into the cap, and pass through the branch passages y y ofthe same into thecup.

The replenishing ofthe cups with oil in figs. 1 and 2, may be eectedafter removing the screwcap B and its adjuncts, which operation does notinterfere with the readjustment of the pin to its proper position, asthe cap on being replaced is screwed down to a solidshoulder, leavingthe pin in its adjusted condition.

Without further description, it will be evident that the importantadvantages of dispensing with the usual Wicks and other imperfectappliances, andof discharging just so much oil from the cup :is isnecessary to meet the demand forpcrfect lubrication' are attained; atthe same time the oil and interior of the cup zn-e maintained' in aclean,lunguu1med state.

I claim as my invention, and desire to secure by Letters Patent- Anoil-cup having an'adjustablc tapering pin projecting through, but freefrom contact with the sides of Yan orifice communicating with andsmaller than the discharge-passage x, so as to form a. regulating-dripor guide for conveying the oil from thc cup to the said passage, allsubstantially as described.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.. v
